I looked at all your tickets and all 5 are completely resolved. The newest one was about billing address capturing, and that was added in 3.0.3 as promised. Before that, it was a category doubling issue in the default theme, and that was also fixed. Before that, you had an issue with QBMS integration, and I released a patch which fixed it. Before that, there was an issue with page navigation, which I also patched. Before that, you had a ticket regarding products not appearing, and it turned out that the products hadn’t been published yet. Before that, on your very first support ticket, you had a CSS issue, which I helped resolve.
So I’ve resolved all your support tickets. Sounds to me like I’ve provided excellent support, but I do appreciate how frustrating issues can be.
If you’re having trouble accessing support tickets, my guess would be that you’re trying to login as a guest (email only) whereas you purchased as a registered user, so also must log in as a registered user. I can help you resolve the access issue if it continues.
